' mammals m 19%?- ss e a ea t- This invention relates. to a novel typewriting machine, which is readily convertibleto use either for continuous billing work or. for ledger-posting, little transforn' ation being required'tof'i-eiider the machine capable of handling either class of work.

According this invention, there is provided web-handling equipment including a displaceable platen-frame, a delivery table anda knife for severing" the typed. formsections of. the web. This inechahism' may be of the character disclosed in the, patent to W'illiain F. 'Helirionld No.

ed February. 9, 1926.

Forfl edger-posting the delivery table is e edge gages which pos tion or locate the ledger-"sheet for the desired entries thereon. The table thus forms a sheetkgaging table. The web 'severing knife is positioned between the sheet-gaging table and the'printing line 'of'the platen, the knife being so constructed that it is manipulatively detachable from the machine, so as not to interfere with the gaging operation incident to the introduction of a ledger-sheet for typing.

When it is desired to transform themachine for ledger-posting, the web may be folded back at the rear. of the machine.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a front view, in elevation, of an Underwood fan-fold combined typewriting and computing machine.

Figure 2'is a cross-sectional view. in elevation, through the line 22 of Figure 1, and shows the machine as applied to fanfold billing-work.

Figure 3 is a diagrammatic cross-sectional view, in elevation, through the center of the machine, showing the machine as applied to ledger-posting work.

Figure 4 is a perspective view, showing the removable feature of the fan-fold knife.

This invention is illustrated as applied to a combined typewriting and computing machine of the fan-fold or continuous billing type. The typewriting mechanism comprises a platen 10, around which a worksheet is fed, by means of co -operating feedrolls 11, to the printing point in front of the platen to be typed upon by means of type-bars 12. The computing mechanism eqpipped with 'a'pair of oppositely-disposed SIC at the front and at the rie ementing, reg st rs, n t bwni nt ol e by th imin r'al-ki ys of the typewriter. Each register is effective in certain computing aone's'fofthecarriage, the carriage being positioned by means of tabulating keys corresppiiding to the'computing. zones.

A web having a plurality of fan-folded plies, upon'each of which plies bill-formsare printed, each form registering with other forms printed'in the underlying plies of the web, is inte rleaved with carbons and is passed over a cross-bar"15, gages 16. The web is then insertedin the h din dge irst, d wn p pertable 17 under and around the platen c6 01),- crat ng wiihf he. eedl s t be ad therearound past the printing point in" front of the platen behind a'knife'18 and up over a front table 19 to be gaged in form-lengths against a gage 20 slidably mounted upon a bar 21 and settable thereon by means of a screw 22. f i

Upon displacing the carbons from the typed forms, the platen is again lowered to its normal position and the platen-frame is locked in position by means of a latch 32 engaging with a pin 33 fast to one of the side plates 23, whereupon the typed forms are torn off against the knife 18.

When it is desired to transform the machine for ledger-posting, the web 14 is withdrawn from the machine and is folded upon the carbon-carrier. The knife 18 is also taken oif the machine preparatory to inserting screw"39.

In the Underwood fan-fold V billing ma- H chine the knife 18 is swingable to a position below its normal cuttingroif position, to serve as a means to guide the leading edge ofthe web. The knife is rockably mounted on the platen-axle 27 and is actuated by a linger-piece 7 having a pin 48, fast thereto, designed to engage cam-slots L9 in the camplates 35. This same feature is retained in the present invention, no changes being made to the knife-operating mechanism.
